Universal type elastic potential energy mechanical catapult for single tandem wing unmanned aerial vehicle with rear propeller

Abstract

The invention discloses a universal type elastic potential energy mechanical catapult for a single tandem wing unmanned aerial vehicle with a rear propeller. The universal type elastic potential energy mechanical catapult comprises a body, a catapulting frame assembly, a projecting frame assembly and an aerial vehicle body structure enhancing projecting assembly fixed to the lower portion of the aerial vehicle. A sliding rail is installed on the body, and a sliding block is embedded in the sliding rail. A catapult switch assembly is installed at the tail end of the body. A winch is installed on the lower portion of the body. Direction-adjustable supporting frame assemblies are installed on the two sides of the body. A roller shock absorption retainer assembly is installed at the head end of the body. The catapulting frame assembly is connected with the upper portion of the sliding block in the sliding rail. A projecting extension device is connected with the upper portion of the catapulting frame assembly, and the aerial vehicle is arranged on the projecting extension device. The aerial vehicle body structure enhancing projecting assembly matched with the projecting extension device is installed on the lower portion of the aerial vehicle body. By the adoption of modular design, the universal type elastic potential energy mechanical catapult is easy to disassemble and assemble and convenient to carry; the projecting extension device and the body can be combined conveniently and flexibly according to practical situations, the adaptability of the catapult to the unmanned aerial vehicle and the environment is improved, and the using efficiency-cost ratio can be effectively increased.

Description

technical field [0001] The invention relates to the field of assisted take-off of fixed-wing unmanned aerial vehicles, in particular to a general-purpose elastic potential energy mechanical catapult for single-wing UAVs with rear propellers. Background technique [0002] At present, many application fields such as military reconnaissance, urban security, and disaster rescue require the intervention and assistance of aircraft. At this stage, UAVs are mainly divided into fixed-wing UAVs and rotary-wing UAVs. Among them, fixed-wing unmanned aerial vehicles are developing towards two extremes, one is larger in size, emphasizing the characteristics of multi-module, high load, and long endurance; the other is smaller in size, emphasizing maneuverability , easy to carry and other characteristics of unmanned aerial vehicles, but small unmanned aerial vehicles with this feature are often designed as aircraft without landing gear (flying wing aircraft) because of their carrying chara...

Problems solved by technology

Among them, fixed-wing unmanned aerial vehicles are developing towards two extremes, one is larger in size, emphasizing the characteristics of multi-module, high load, and long endurance; the other is smaller in size, emphasizing maneuverability , easy to carry and other characteristics of unmanned aerial vehicles, but small unmanned aerial vehicles with this feature are often designed as aircraft without landing gear (flying wing aircraft) because of their carrying characteristics, or their take-off surface is often in the wild environment, unable to Take off with conventional landing gear

In addition, in terms of aircraft: due to the multi-tasking requirements of the above-mentioned small unmanned aerial vehicles, the quality of the whole machine has an upward trend, which has brought many limiting factors to the successful manual throwing take-off; in terms of operators, the design of small unmanned aerial vehicles One of the purposes of the aircraft is portability. Under the limitation of manual throwing and take-off caused by objective factors, the portability, ease of operation and superiority of the tool's cost-effectiveness are particularly important.
